Specification of Letters Patent.

Patented Sept. 15, 1908.

Application led November 25, 1907. Serial No. 403,823.

T o all whom it 'may concern.'

Be it known that I, CHARLES E. VARNUM, a citizen of the United States,residing at Lawrence, in the county of Douglas and State of Kansas, haveinvented a new and useful Heater, of which the following is aspecification.

This invention relates to ortable heaters of that general class especialy designed for use in carriages, wagons, automobiles, sleighs and othervehicles and has for its object to provide a comparatively simple andinexpensive device of this character which per-` forms the dual functionof a hand and foot warmer.

A further object of the invention is to provide a heater including acasing having spaced longitudinal partitions defining superposed heatingcompartments, there being perforations formed in the end walls of thecasing to permit the free circulation of air through said compartments.

A further object is to provide a hood or shield for deflecting the hotair from the burner laterally and downwardly into contact with thepartitions so that the hot air may be distributed uniformly throughoutthe casing. .i

A further object is to provide improved means for locking the lampwithin the casing, and means for regulating the size of the flame at theburner tip.

A still further .object of the invention is generally to'improve thisclass of devices so as to increase their utility, durability andefficiency.

Further objects and advantages will appear in the following description,it being understood that various changes in form, proportionsand minordetails of construction may be resorted to within the scope of the apended claims.

n the accompanying drawings forming a part of this' specification:Figure 1 is a perspective view of a heater constructed in accordancewith my invention. Fig. 2 is a longitudinal sectional view of the same.Fig. 3 is a transverse sectional view taken on the line 3*3 of Fig. 2.Fig. 4 is a bottom plan view of a portion of the casing.

Similar numerals of reference indicate corresponding parts in all of thefigures of the drawings.

The improved heater forming the subject matter of the present inventionincludes a casing or housing having a flat perforated base 5 and asemi-circular top or cover 6, the metal forming the base 5 having itsopposite transverse edges bent upwardly to form perforated walls 8 anditslongitudinal edges bent laterally to produce longitudinal flanges 9.

The cover 6 is ofi` set at 1 0 lto forni a pocket for the'reception of astrip of asbestos or similar insulating material 11, the latter beingcovered by a jacket 12 preferably formed of carpet or similar materialso as to give the heater a neat attractive appearance as well as to forma yieldable treadsurface.

The metal forming the top or cover 6 is provided with spacedcircumferential strengthening ribs or corrugations 13 while the oppositeends of the metal are extended longitudinally beyond the end walls 8 andthence bent inwardly to form grooves 14 adapted to receive suitableflanges 15 carried by the end walls thereby to lock the cover in engagement with said end walls.

The opposite ends of the flanges 9 are bent to form laterally extendingretaining ears 16 which are riveted or otherwise rigidly secured to theadjacent end walls, as indicated at 17, the metal forming the rooves 14being cut away to accommodate t e ears 16, as shown.

The opposite longitudinal edges of the cover 6 are bent to form verticalflanges 13 which engage the flanges 9 and form longitudinal grooves forthe reception of the adjacent lower edges of the insulating material andfabric jacket whereby the several parts may be clamped together when theears 16 are s ecured to the adjacent ends of the casing.

Arranged within the casing are spaced longitudinal partitions 19 and 2Odefining a plurality of superposed heating com artments, said partitionsbeing formed wit o enings 21 so as to permit the heat from the amp orburner 21 in the lower compartment to pass through the openings in thepartitions to the upper compartment.

Arranged in the u per heating compartment is a hood or shie d 22provided with laterally extending lugs 23 which are riveted or otherwisesecured to the upper partition 20.

The hood or shield 22 extends longitudinally of the casing and isprovided with o po'- sitely disposed openings 24 through w ich the hotair passes in contact with the reinforced walls of the cover.

The heater 21 is preferably in the form of a lamp the body portion ofwhich is seated in a circular opening -25 formed in the bottom of thecasing and is provided with laterally extending lugs 26 which engage thereinforcing flange 27 of the opening 25, there being oppositely dis osedrecesses -or depressions 28 formed in tie walls of the opening 25 sothat by forcing the lugs 26 upwardly at the depressions 28 and thenartially rotating the lamp the latter may bellocked in position onthebase of the casing.

The burner 29 extends through alined openings 30 formed in thepartitions 19 and 20 and is provided with a removable cap 31 having oneor more bars 32 secured thereto and extending transversely across thewick so as to regulate the height of the flame at the burner tip,

Mounted on the burner tube 29 and preferably bearing against the lowerpartition 19 is a removable disk or collar 33 preferably formed ofasbestos or other suitable insulating material.

The base of the casing is preferably reinforced and strengthened by oneor more transverse ribs 34, the metal at the opposite ends of the casingbeing pressed downwardly to form depending feet 34 which serves tosupport the base of the casing in elevated position above the bed of thecarriage or other.

suitable support.

In operation the lamp is filled with alcohol or other fluid and insertedin the opening 25 in the base of the casing by rotating the lamp untilthe lugs 26 register with the recesses or depressions 28 after which thelamp is partially rotated which causes the lugs V26 to engage thereinforcing flange 27 and thus lock the lamp in position in the lowercompart ment of the casing.

It will thus be seen that the hot air will strike the hood or casing 22and be deflected downwardly into contact with the upper longitudinalpartition 20 and thence pass through the perforations 21 to theintermediate and lower compartment, the fresh air at the same timeentering the casing through the perforations in the end walls thereofthus permit ting the free circulation of air both longitudinally andvertically of the casing.

Attention is here called to the fact that the lower longitudinalpartition 19 is provided Awith depending supporting flanges 35 whichbear against the interior Walls ofthe casing at the base of the latterand engage similar flanges A36 formed on the upper partition 20 andserve to 'force the flanges 36 in engagement with the side walls of thecasing thereby to prevent accidental displacement of the same.

The heater is provided with a suitable handle or Enger piece 37 by meansof which the casing may be conveniently transported from place to place.

The heaters may be made in different sizes and shapes and used as eithera foot or hand warmer.

on converging lines with their terminal por-- tions disposed in contactwith each other and resting on the base of the casing, said partitionsbeing provided with vertically alined openings, a lamp seated in one ofthe heating compartments and provided with a burner extending throughthe openings in the partitions, and arhood disposed within the uppercompartment at said burner.
